Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called tram operation management system in which operation information is transmitted and received between a roadside device and an on-vehicle device, and the operation of a tram is centrally controlled by a central device. On the other hand, the present invention relates to a method for automatically setting and correcting the traveling direction of a train.

2. Description of the Related Art A tram operation management system has the principle shown in FIG. That is, while providing a roadside antenna 32 for uphill and a roadside machine 33 connected to the central device on the uphill platform 31 at the stop,
The down platform 34 is provided with a down-road antenna 35 and a road device 36 connected to the central device, while each of the up and down trains 3
In-vehicle antenna 39 and in-vehicle device 40 are installed on 7,38,
When the up train 37 enters into the communication area W of the up road antenna 32, the up train on-vehicle device 40 and the up road device
When the down train 38 enters the communication area W of the down road antenna 35, it sends and receives information to and from the vehicle 33 of the down train and the road device 36 of the down train. The respective trains are operated according to the operation command information sent from the central unit, and the approach guidance service or the like at each stop is implemented.

Problems to be Solved by the Invention In the case of the operation management system of the above-mentioned tram, the up train needs to communicate only with the on-road machines for the up, and the down train needs to communicate only with the on-road machines for the down, As is clear from FIG. 2, the communication areas W of the roadside antenna 32 for uphill and the roadside antenna 35 for downhill usually extend to opposite lanes. For this reason, it is necessary to devise so as to prevent erroneous communication with the tram in the opposite lane.

The present applicant has invented and applied for a patent for a method of preventing such an erroneous communication with a tram in the opposite lane. In this method, in FIG. 2, a direction code indicating an up / down direction is added to the call signal issued by each of the roadside machines 33 and 36, and the in-vehicle device 40 also receives the up / down direction according to the traveling direction. The traveling direction information is stored, and it is configured to respond to the calling of the roadside machine 33 or 36 when the direction code in the call signal received by each vehicle-mounted device 40 and the traveling direction information of the vehicle-mounted device match. . When using such an incorrect communication method,
It is indispensable to accurately identify the traveling direction of the own train and store it as traveling direction information in the vehicle-mounted device.
For example, as one method, it is the simplest and simplest method that a human intervenes every time the driving direction of the train changes and sets the traveling direction information each time. The operation is troublesome, and there is a possibility that setting may be forgotten. On the other hand, it is also conceivable to use the up / down direction code included in the call signal issued by the on-road machine, but in the communication by collating the direction code, the traveling direction of the train is accurately set and stored in the in-vehicle machine in advance. The assumption is that For this reason, when driving back, etc., unless the traffic direction information of the train is set to be switched to the regular traveling direction before communication, the call signal of the roadside machine in the opposite lane is directly responded as a regular call signal. Will end up. Therefore, the direction code of the train cannot be switched and set by this direction code.

The present invention has been made under the above circumstances, and provides a method for automatically setting and correcting the traveling direction of a tram.

Means for Solving the Problems The present invention is configured such that when a tram leaves a garage, it is always configured to leave either one of an up line and a down line, which is defined as one line, and The tram has two driver's seats, one at the front and the other at the rear, and is configured on the premise of two facts that the driver's seat is switched back and forth whenever the driving direction changes.

That is, the present invention is a double-track type tram that exits toward either one of the upward line or the downward line when leaving the garage, at each stop, for uphill connecting to the central device. By providing a roadside machine and a roadside machine for downlink, wireless communication is performed between the roadside machine for the up train and the roadside machine for the down train, and the information for the information between the on-board machine of the train by communicating with the road machine for the down train. In an operation management system that exchanges and operates a tram according to various operation command information sent from the central device, a leaving roadside machine is provided on the outgoing line of the garage, and when the train leaves the car, When communication is performed, the traveling direction information of the in-vehicle device of the leaving train is forcibly set to either the ascending or descending direction corresponding to the leaving direction, and the driver's seat of the train is switched back and forth during driving. , This The traveling direction information of the vehicle device is obtained to switch in the opposite direction.

Action All the exit trains leave the train towards the designated track, either the up or down line. Therefore, by setting the traveling direction information of the in-vehicle device to the up or down direction determined above when the in-vehicle device of the leaving train communicates with the on-road device provided on the delivery line, the traveling direction information of the train to be delivered. Can be set in the right direction, even if is set incorrectly. In addition, when the train is driven in the opposite lane for turning back and forth, the driver's seats used are switched back and forth, and the rear driver's seat, which used to be the rear side of the vehicle until now, becomes the front side of the vehicle and is turned around. . Therefore, for example, if the traveling direction information is switched to the opposite direction on the condition that the driving key switches in the front and rear driver's seats are switched, the actual traveling direction of the train and the traveling direction information of the vehicle-mounted device are automatically matched. be able to.

Example Hereinafter, the method of the present invention will be specifically described with reference to FIG.

1 is an up line, 2 is a down line, 3 and 4 are crossovers for switching trains between up and down to perform turn-back operation,
5 is an entrance line for putting the train into the garage 6, 7 is an exit line for leaving the train from the garage 6, 8 is an up platform at the stop, 9 is a down platform at the stop, and 10 is an up line provided at the up platform Road antenna (the main body of the road machine is omitted. The same applies to the following), 11 is a down road antenna installed on the down platform, 12 is a warehousing antenna for the road machine for warehousing provided in the middle of the warehousing line 5, and 13 is warehousing. A delivery antenna of a roadside device for delivery provided in the middle of the line 7 and an onboard antenna 14 of an onboard device (the main body of the onboard device is omitted) mounted on the train C.

Incoming and outgoing lines 5 and 7 for moving the train C into and out of the garage 6
Is connected to either the up or down side track (downline 2 in the illustrated example) in order to unify the vehicle maneuvering work and prevent collisions, etc., and trains entering and leaving always go in the down direction. Is considered.

In the above structure, the present invention is realized as follows. That is, when starting the operation of the train, the driver, after performing the start-up inspection and the like, gets on the driver's seat on the front side and exits the garage 6, and proceeds on the exit line 7 toward the down track 2. When the train C enters the communication area of the exit antenna 13, the in-vehicle antenna 14 receives the operation information from the exit roadside device, transmits the departure information from the in-vehicle device to the exit roadside device, and manages the operation by the central unit. Is started.

The in-vehicle device of the train C that has received the information from the above-mentioned roadside device for shipping sets the traveling direction information of the in-vehicle device to the down direction information by the command information included in the information. Generally, the train destination, the traveling direction information, etc. are set by the driver at the time of the start-up inspection, but even if the traveling direction information set due to an erroneous operation or forgetting the setting is in the wrong direction, according to the present invention, When passing through the exit antenna position, it is always forcibly set to the down direction, and the traveling direction information of the exit train is always corrected to the correct direction.

The train C enters the down line 2 as described above and starts down driving.

For example, when the train C that is currently driving down gets into the ascending line 1 through the crossover line 3 due to a turn-back operation, the train C is a branch point 3a on the ascending line 2 side of the crossover line 3.
After passing the vehicle in the down direction, the driver moves from the driver's seat on the front side to the driver's seat on the rear side of the vehicle, and the driver's seat that has been the rear driver's seat until now becomes the driver's seat on the front side. Fork
You get on the train C from 3a to the branch point 3b, and finally cross the branch point 3b and enter the down line 1. That is, the down line 2
Therefore, the train C boarding the up track 1 is switched around at the turn-back position. Therefore, when the driver's seat is replaced front and rear, the traveling direction information stored in the vehicle-mounted device is corrected from the downward direction to the upward direction based on the replacement of the driver's seat. As a result, the traveling direction information of the train C is automatically corrected in the correct direction even during the turn-back operation. The simplest and surest way to know the change of the driver's seat is to use ON / OFF of the driving key switch provided in each of the front and rear driver's seats.

EFFECTS OF THE INVENTION Since the present invention has the configuration as described above,
The traveling direction information of the train that is set and stored in the in-vehicle device of the tram that is operated under centralized control by the operation management system can be set and calibrated to always match the actual traveling direction. It has an excellent effect that the communication according to the traveling direction of the road machine can be made more reliable and the operation management of the tram can be further improved.
